Which of the following murmurs increase with Valsalva maneuver?
Correct Answer: Hyperophic cardiomyopathy
Description: Hyperophic cardiomyopathy is defined as left ventricular hyperophy that develops in the absence of causative hemodynamic factors, such as hypeension, aoic valve disease, or systemic infiltrative or storage diseases. Patients may be diagnosed after undergoing evaluations triggered by the abnormal physical findings (murmur) or symptoms of exeional dyspnea, angina, or syncope. Alternatively, diagnosis may follow evaluations prompted by the detection of disease in family members.The systolic ejection murmur of left ventricular outflow tract obstruction is harsh and late peaking and can be enhanced by bedside maneuvers that diminish ventricular volume and transiently worsen obstruction, such as standing from a squatting position or the Valsalva maneuver.Ref: Harrison; 19th edition; Page no: 1569
